Is it possible to ignore any empty groups within a multigroup when submitting a node? There are a couple instances where this would be helpful:
1) If any field in a group is required, the node will not save until the empty group is removed. It would be more user-friendly to simply ignore the empty group.
2) If an empty group appears in the middle of two non-empty groups (for instance, if you move an empty group between two non-empty groups, or add two empty groups but only enter values for the bottommost one), then an empty row appears when you view the node. Again, it would be more user-friendly to just ignore that empty group.
